316 G. C. KAROP ON SPECIALISATION IN CYTOLOGY. 



C. Cytophysiology. 



Tlie doctrine of the living phenomena of the cell. This is 

 further divided into : — 



a. Cytomeohaiiics. 



The physical properties of the cell and its behaviour to 

 mechanical stimuli, further divided into : 



1 . Cytostatics, 



A science which has not yet been cultivated, at least from 

 a zoological standpoint, and which concerns the conditions of 

 equilibrium of the cell and its structures. 



2. Cytodynamics. 



The doctrine of the phenomena of motion in the cell. With 

 this is included the phenomena of cell-division, maturation, and 

 fertilisation, the death of the cell, and in great part also the 

 pathology of the cell. 



h. Cytochemistry. 



The chemistry of the cell might be divided into static or 

 constitutional and dynamic. To static chemistry would belong 

 the investigation of the chemical properties of the plasma and 

 nuclear substance. To dynamic chemistry falls the processes of 

 cell-metabolism.
